    I see lots of good options described in the above posts and nice pics of cars here(BMWCurves) , but I'm also still considering just staying with the OEM Sachs to be on the safe side(for the next 7 years). I need the suspension primarily to soak up the moderately bad roads and still allow me to drive fast on highways and corner well. I don't have a lot of time to decide as the strut mounts are making lots of noise and my day off to go the shop is late next week. Thanks guys..
    If nothing else, I'd go Koni (either Sports/yellows or the FSDs) over the OE Sachs because they last longer and have a lifetime warranty. My factory Sachs were completely shot when I removed them at 10 years and only 50k miles. You can't go wrong with Koni.

    Also, those descriptions of drops in ride height on TireRack due to the Eibach springs are normally for non-sport package equipped cars, meaning the drop should be less for our Performance Package (ZHP) cars. A few members have Eibach springs, they can tell you what they experienced.

    If you don't want to go lower then run the FSDs on the stock springs. I had FSDs on my coupe (with the Eibach sport springs) and the overall ride and handling were improved tenfold over stock. I will certainly upgrade to FSDs myself once the suspension needs to be refreshed.

    Webster: do you have any pictures of your car from the side to share, so I can see the lowering and wheel gaps? I have been looking at internet E46 pictures of the Koni FSD and especially with the Eibach Pro Kit springs on them. I had the Bilstein sports shocks and H&R sport spring on my prior car, I like the cornering, and braking stability and they did not wear after 7 years but hated going over bad city roads everyday and watching out for bottoming the front.

    The good thing about non-oem shocks is they tend to last longer than OE and suspension work is the biggest cost on my E46 so I'm trying to get the setup correct for my needs. Thanks.

    Here you go. The rears would rub on big bumps only if the car was fully loaded (i.e. Trunk full of suitcases and passengers in back seat). 99% of the time it was not an issue. The wheels are staggered ARC-8s (rears are 18x9 ET 42).

    It's been 3 months since I decided to go with the FSD and the stock OE springs. One of the best decision I've made, with the forum's help.
    The car is leveled evenly. It takes bumpy uneven roads and expansion joints well. I've not have hit bottom yet. It corners well and rigid for my crazy zip-zig freeway driving style. Very competent and assuring.

    I recently took it to a highway and the limit was that it takes medium curves well at up to 90mph. Any faster, well I have to start using the brakes. It sucks though that I get passed by a Nissan Z on curvy roads. The ZHP is not meant to be a sports car. It does everything I need it to do. Here's a pic.
